PLOW.

Specification of Letters Patent.

Patented. July 21, 1908.

Application filed April 18,:1906. Serial No. 312,351.

To all whom it may concern:

Be it known that I, SAMUEL H. TINSMAN, a citizen of the United States of America, and resident of Fort Madison, Lee county, Iowa, have invented a certain new and useful Improvement in Plows, of which the following is a specification.

My invention relates to improvements in plows of the wheeled or sulky type, and has for its object, generally stated, the provision of a simple and durable construction, in combination with certain novel details, thereby to increase the general eiiiciency of the plow; and a special object of my invention is to provide an improved foot-lift, whereby a wide range is given to the vertical movements of the plow, and the same is easily controlled; and a further object is the provision of a'positive locking means, whereby the plow may be positively secured in any required position, and by which the rocking depth of the plow may be varied at will.

These and such other objects as may hereinafter appear are attained by my invention, an embodiment of which is illustrated in the accompanying drawings, in which Figure 1 is a plan view of my improved plow. Fig. 2 is a side elevation of the same.

Fig. 3 is an enlarged detail of a portion of Fig. 2. Fig. 4 is a vertical cross-section on line 44 in Fig. 3, looking in the direction indicated by the arrows. Fig. 5 is a horizontal cross-section on line 55 of Fig. 4, looking in the direction indicated by the arrows.

Like figures of reference indicate like parts in the several figures of the drawings.

Referring now by figure to the accompanying drawings, 1 represents the plow; 2 the point of the plow; 3 the heel of the plow 4 the plow beam; 5 the land-side wheel; 6 the furrow-side wheel; and 7 the colter wheel. The frame 8 is mounted on the wheels through the medium of posts 9 and 10, and the support 11, which latter support is secured to the bail-shaped axle 12 to which the plow beam 4 is journaled. The furrow side of the axle is journaled to the brace-bar 13 of the frame by an ear 14. The land side of the axle is connected to the land-side wheel through the medium of a crank-bar 15. The seat 16 is secured to the frame by a spring support 17. A connecting bar or bearing 18 unites the bail with the frame, being secured to the frame by a bolt 19. This bar terminates in the rack 20 secured between the ears 21 of the spring container 22, which latter is secured to the lever 23. A locking bolt 24 is secured to the end of a rod 25 which is operated by the usual bellcrank lever 26 attached to the handle of the lever 23. A spring 26 is seated in the'container 22, by means of which the locking bolt 24 is kept in engagement with the rack 20. A supplemental arm or rack 27 is swingingly secured to the frame, which passes through an eye 28 in a supporting bar or foot lever 29 secured on the axle at 30. The end of the arm 27 is racked, as shown at 31, and a bolt 32 passes through the forks 33 and 34 of the bar 29 and normally engages the rack teeth 31.

Mounted on the arm or foot lever 29 is a short lever 35, preferably fulcrumed on the bolt 32. The bar portion of this lever 35 is turned inwardly at right angles, forming a disengaging bar 36. The lower arm of the lever 35 is turned outwardly at right angles, forming a finger 37 extending under the arm 27 and ada ted to engage it and raise the rack out o engagement with the bolt 32.

The upper end of'the bar or foot lever 29 is formed into a horizontally extending footrest 38. The foot-lift 39 is rigidly secured to the end of the axle 12 and provided with a foot-rest 40.

The crank arm 15 is loose on the axle 12, and the lever 39 is adapted to swing above the spindle 41 of the land-side wheel 5. WVith this arrangement, the hand lever 23 is rigid with the arm 15. In this way the wheel 5 can be controlled by said hand lever while the plow and .axle 12 remain locked by the rack 31 relatively to the frame of the plow.

Referring to Fig. 2, the plow is shown in normal position out of the ground. If it is desired to force the plow into the ground, the lever 23 is pushed forward to the end of its throw and locked in position by means of the locking-bolt 24 engaging the ratchet 20. At. this time the armor foot rest 29 is held locked in lace by means of the bolt 32 engaging the rac: 31. If it is desired to force the plow still dee er into the ground, the operator laces his foot on the rest 38 and the toe of iiis boot on the disengaging bar36. By ressing down on this bar, the finger 37 is orced against the rack arm 27, throwing it up, and throwing the rack 31 out of engagement with thezbolt 32. Theloperator thenjdcks forward with his foot still on the rest 38, thereby forcing the axle outward and the plow deeper into the ground. By removing the pressure of the toe from the bar 36, the arm falls down and is automatically locked in position by means of the bolt 32 engaging the rack 31. In this way the low and beam are locked in up and down and intermediate positions rela tively to the frame.

This device is of great value, as it enables the operator to easily regulate the depth of the furrow.

The foot levers 29 and 39 are both rigid with the axle 12-, which latter extends forward in the form of a bail. Said foot lever 39 can be pressed down to rock the axle or bail 12 and thereby raise the plow in the frame. The spindle 41 is not rigid with its axle 12, but is movable relatively thereto, for the urpose of manipulating the land-side whedl while the plow and frame are locked together.

While I have shown my improved foot lift in connection with a plow, I do not, for the broader purposes of my invention, limit my with a plow and beam, a frame, supporting wheels, an axle secured to said plow beam, a hand lever mounted on said axle, a land-side wheel controlled by said hand lever, a foot lever rigidly secured to said axle, an arm mounted on said frame and provided with a rack portion, and means carried by said foot lever for engaging said rack portion to lock said axle in the desired position.
